The Server kernel uses large memory pages to get up to 64GB usable.

In today's OS an d machine setup... you will never see it.

There is also nVidia Kernel Modules you'll need to load.

The Generic Kernel CAN ONLY use about 3.5GB of memory if you are lucky.

Dump i386 and the generic kernel

First boot selecting the server kernel.

Hit ESC before it boots and select it.

I've not seen any real benefits with 64bit except when I have 32GB or more memory and all of the programs running on the machine are compiled for only 64-bit... other wise you'll have to have both 64-bit and 32-bit extensions/libraries on the machine and you;ve effectively eliminated any real benefit.

For about another year or so, I'll be sticking with 32-bit and large pages enabled. After than, I'll try it again.

thing...

You have to install the 64-bit libraries and many other pieces to flip to the 64-bit kernel.

It might be eaiser to just install with 64-bit versions.

Yeah, I know. You and OSes and hardware... bad combo.
